I held two strands of worsted weight yarn together to do this project. Using size 15 needles:

CO 28 sts
Using first color, K2, P2 for 30 rows
Switch to second row, and follow pattern until it is 30 rows less than desired length
Switch back to first color and work 30 rows
BO

I finished this scarf really fast! It only took me two days and I wasn’t working on it the whole time.
